    名称:
    2H NMR evidence for dynamic disorder in human skin induced by the penetration enhancer azone
    摘要:
    Penetration enhancers mediate trans-dermal drug delivery. The penetration enhancer dodecyl-azacycloheptanone (Azone(R)) was characterized in situ with H-2 NMR on human stratum corneum treated with either uniformly deuterated Azone(R) or penetration enhancer with only the entire chain deuterated, in both cases in propylene glycol. The H-2 NMR spectrum at ambient temperature constitutes a single narrow line only 180 Hz wide. This contrasts with the complex lineshapes 1-25 kHz wide commonly observed for methylene deuterons of lipids in a bilayer gel phase, Hence there is no evidence for differences in orientational behaviour between different deuterons at ambient temperature. The narrow line translates into a low overall order parameter S-CD < 0.0008, for all deuterons, revealing rapid motion of the entire enhancer with correlation times tau(c) much less than 6 x 10(-6) s, in all possible directions. At temperatures of about 150 K a H-2 NMR pattern characteristic for a random isotropic powder was observed on samples of stacked stratum corneum sheets at different orientations with respect to the magnetic field. This provides strong evidence for random isotropic freezing of the Azone(R) molecules upon cooling. The H-2 NMR data suggest than incubation with Azone(R) in propylene glycol provokes dynamic structural disorder of the intercellular lamellar lipid structure throughout the stratum corneum and possibly even the creation of fluid domains involving the intercellular lipids, which may be essential for the penetration enhancing effect.

    日期:2016.10
    The synthesis of 12 deuterated ceramides with either a deuteration at the last carbon atom of the amide bound fatty acid or a perdeuterated fatty acid chain is described. The ceramides were prepared starting from sphingosine or phytosphingosine and ω deuterated or perdeuterated fatty acids with PyBOP® as activating agent in high yields. For the synthesis of the specifically deuterated fatty acids,

    Significance

    We have solved a long-standing mystery of the biosynthetic origin of 1-undecene, a ubiquitous hydrocarbon semivolatile metabolite of Pseudomonas . Our study revealed an unprecedented family of nonheme oxidases that specifically convert medium-chain fatty acids into the corresponding terminal olefins using an oxygen-activating, nonheme iron-dependent mechanism. Our findings unveil previously unidentified chemistry in the nonheme Fe(II) enzyme family, aid the functional study of this ubiquitous metabolite in Pseudomonas , expand the scarce enzyme inventory for the transformation of fatty acid precursors to hydrocarbons, and serve as the basis for engineering efforts to establish bioprocesses to produce medium-chain terminal olefins, useful as fuels and chemical building blocks, from renewable resources.

    manner that reflects decreased fatty acid binding affinities. Anaerobic isotope exchange experiments provide compelling evidence that Tyr379(•) initiates catalysis by H(•) abstraction. C(α)-H homolysis is kinetically driven by O(2) trapping of the α-carbon radical and reduction of a putative peroxyl radical intermediate to a 2(R)-hydroperoxide product. These findings add to a body of work which establishes

  • Modular synthesis of bis(monoacylglycero)phosphate for convenient access to analogues bearing hydrocarbon and perdeuterated acyl chains of varying length
    作者:Meng M. Rowland、Michael D. Best
    DOI:10.1016/j.tet.2009.06.085
    日期:2009.8
    Bis(monoacylglycero)phosphate is an important phospholipid that controls the structure of late endosomes as well as biological activities that occur there. The study of this lipid is complicated by the fact that acyl migrations are known to generate different regioisomers. Herein, we describe a modular synthesis of 3,3'-BMP derivatives that allows for the incorporation of a range of different acyl chains at a late stage. This approach was exploited to produce eight BMP analogues bearing normal saturated and perdeuterated acyl chains of varying length. (C) 2009 Elsevier Ltd. All rights reserved.
